[Rd] Persistent data structures for R

[hadley wickham]

Hi all,

Has anyone thought about developing persistent
(http://en.wikipedia.org/wiki/Persistent_data_structure) "functional"
data structures for R?  A persistent data frame, for example, would
seem like a possible way of drastically reducing memory consumption
for many common problems.  Would developing a family of a few such
algorithms make for a good summer of code project?

Regards,

Hadley
